Short answer
No. It doesn't fit in memory.
Needs ≈50 GB but only ≈25 GB is available after the OS, other apps and Open WebUI.
Why it doesn’t fit
Even its smallest practical version (3-bit) needs about 50 GB for the model, its context memory and the runtime. After macOS (≈3.5 GB), a browser with a few tabs (≈3.0 GB) and Open WebUI (≈1.0 GB), MacBook Air M4 32 GB has about 25 GB left, so it’s 26 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 23 GB short.
